JR gracefully uses his quick wit with his entertaining personality to share lessons of struggle, triumph and the power of believing in yourself to make your dreams come alive. His musicianship has helped define the pop, R&B and Jazz era for the last half century, making him one of the most recorded drummers in history. No one will forget JR’s landmark “drum fill” which opens the iconic song, “Rock With You,” (from Michael Jackson’s Off the Wall) which is and will always be an essential piece of pop music lore. From stories of the making of one of the highest grossing songs of all time, “We Are the World”, to the first time he met Quincy Jones, (who provides the foreword), to touring with Peter Frampton, working with Usher, Daft Punk, a heart-breaking story with Barbra Streisand, plus 60 more A-list musicians and producers’ stories. King of the Groove is a highly enlightening book that will delight and inform musicians, music fans and entrepreneurs alike. A tour de force experience from beginning to end.
